Optical Fiber Personal Computer Data Transmission system for Local Area Networking

摘要

This paper describes an improved optical fiber transmission system for the personal computer data through analog telephone modems and optical links.The modem is internally connected to the optical link so that the transmission through the optical fibers is complete. The system is constructed using square-wave frequency modulation (SWFM) scheme for digital data transmission before the electrical output obtained from the modem in fed to the electrical-to-optical conversion. The system was successful when digital data was transmitted over 3500m using multimode GI optical fibers.
